To'clZZ wlw/m 'it may conce/1% Be it known that l, LLEWELLYN donne, acitizen of the United States, and resident of New Castle, in the countyot Lawrence and State of Pennsylvania, have invented certain new anduset'ul improvements in rllinningr and Galvanizing Machines, oit whichthe following is a specification.

My invention relates to tinning and galvanizing machines, and moreparticularly relates to the brushes or'wipers for the feedout rolls, andhas for one ot its objects,the provision of a supporting or reinforcingmember tor said brushes.

Another object isI to provide a supporting or reinforcing member that'will'no-t interere with the adjustment ot thefwipers orv their generaloperation.

The Wipers or brushes used to clean the feed-out rolls intinuingmachines are pretyerably made of asbestos 0r. the like, rein forced bywire, and are' of comparatlvely light structure. rlhes'e brushes aremounted for adjustment relative to the rolls, and

i hereto-fore such brushes have worn unevenly and become .useless due totheir being adjusted or tightened against the rolls in orf der toeconomize on inetal. Also the brush when tightened too much `will doubleunder the roll making imperfect cont-act, and not onlyv makingthat partof the brush useless, but also producing westers' or cobbles.

@ne object ot this invention is to provide a reinforcing bar that will.cause the brush' to wear more evenly, and to positively preventdoubling' under the action of the rolls.

Referring to the drawings formingpart .et this Specification, Figure lis a sectional side elevation of a tinning pot provided with my improvedreinforcing members, on

the line ll-ll of Figure 2.

Figure 2 is a sectional plan on the' line lll-ll ot Figure l.

-V Figure 3 is `a plan on a larger scale showingldetails intheconstrucition of the side trames et the feeding mechanism.

Y Figure l is a side elevation of the appa-s ratus otlFigure 3.

Figure 5 is a sectional end elevation showing details in theconstruction of nny iinproved apparatus.

ln the drawings, the numeral 2 designates a tinningor galranizing1 potin which the tin,- spelte-r, or other (mating,I material is maintainedin a molten condition. The pot, as shown, is provided with guides 3, Il,and 5, and guides 6 and 7,18 and 9, by means of whichthe forward ends otthe sheets or plates being coated are directed 'into the .bit/e of oneor the other of' the twosets ot "feed-out rolls shown. 'lhe lojwer setso'l teedout rolls l() and ll, l2 and 13, engage with, and feed thecoated sheets or lplates upwardly into the bite ot the upper sets otfeed-out rolls la andl, and i6 and' l?, respectively.

rllhe rolls are rotatably mounted in adi j ustable bearings 18 which aremounted for transverse adjustment between. riderV plates l2 and 20011.each end cie the ot 2.

Suitable bent levers 2l, provi ed for transversely adjusting the rolls,are pivotally mounted on bearings 22 and each has its lower end inengagement with one ot the bearings 18, and their other end inengagenient with adjusting nuts 23 on screw threaded standards 24C. Byadjusting` the` nuts 23 the levers 2l will be rocked upon theirrespective bearings 22, thus moving their lower ends toward or away fromthe slide bearings -18, causing an adjustment thereof.

The top set ot feed-out rolls lll! and 15,' 16 and 17, are provided withwipers or brushes 25 which engage the roll tas 'and remove anymolten-metal adhering thereto, so as to assist i-n maintaining the rollsin operative conditions and 'prevent damage 'Titi' to the surfaces otthe coated materials passed A between the rolls. j

The brushes 25 are composed ot a .plurality of strips of asbestos or.the like, be-

veo

tween bindingl plates 25a which are secured together by bolts 25b andare mountedy on spring pressed supporting` arm members 26 which areadjustably mounted in the angle iron members 2f? mounted adjacent to thetop edge of the ends of the pot. f

'Reinforcing bar members29 entend parallel with the ybrushes 25 and inclose proaimity thereto, and are mounted in the slots 30 in the riderplate 20. Th# reinforcing; bars 29, as has been said, eri/end parallelwith the brushes and extend upwardly to the rolls forming1 a positivestitening or reintorcing member for the brushes.

lll/hen the brushes are tightened to have rmore pressure against therolls'they ywill have va tendency to buckle or double, due to the guides3,4@ and 5, and pass on through one of the sets of guidesy 6 and 7, or 8and 9, into their respective feed-out rolls 10 and I l1, or l2 and 13..rlhe rollers l0 and 1l7V or' l2 and 13, are purely squeeze rollers andre- .move excess tin.

rllhe plates "'or'sheets then pass up and are r, engagedbetween thefinishing rolls which are kept clean and smooth by the brushes 25.

rlhe principal advantage of my improved device is in the positivereinforcing of the brushes 25 Without interfering with their flexibilityor adjustment and the simple manner in which this result isaccomplished.

l claim l. rllhe combination with a tinning, pot mavifieiegeoe brushesfor said rolls, of a reinforcing barn seperate and apart from saidbrushes. adapted to prevent doubling thereof.

2. The combination With a tinning pot machine having tinning rolls andcleaning brushes for said rolls', of reinforcing bars running parallelwith each of said brushes, said bars Ibeing separate and apart from saidbrushes.

3. V The combination With a tinning pot machine having rider platesmounted adjacent each end thereof, a plurality of rollsmounted'betweensaid plates, and vcleaning brushes runningparallel-Witheach of said rolls and adapted to engage the surfacethereof, of reinforcing bars running parrallel With each of saidbrushes', said -bars being mounted in slots in said rider plates andbeing separate and apart from said brushes. ln testimony whereof l havehereunto set my'hand.
